DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a method for arbitrarily extracting a desired portion of recorded program information from a disk serving as an information recording medium on which program information is recorded, such as a digital audio disk. The present invention relates to a disc player capable of selective reproduction.

2. Description of the Related Art A digital audio disk (hereinafter referred to as a digital audio disk) is a rotating disk-shaped recording medium in which an audio signal is digitized and recorded as program information to form a spiral recording track.
DAD) is used, and such DAD is played on a disk player to reproduce playback program information,
That is, a DAD system capable of obtaining a reproduced audio signal is becoming more and more popular as an audio signal reproducing system capable of obtaining a high-quality output audio signal.

In such a DAD, the recorded program information is, for example, in the form of a collection of a plurality of segmented program information, each corresponding to each piece of music, and usually the address data is accompanied. This address data may be, for example, data representing the recording arrangement order from the playback start end side of each segmented program information, data representing the order of subdivisions within one segmented program information, or data representing the position on a spiral recording track. It includes various data such as data representing the playback time from the start of playback. Since such address data is recorded along with each section of program information, when reproducing program information from the DAD, the reproduction address data is used to locate a desired location in the program information. For example, specific section program information can be selectively played back.

For this reason, a disk player used to obtain playback program information from a DAD has not only an operating mode in which a plurality of segmented program information recorded on a DAD are sequentially played back from the playback start end in accordance with the recording order. For example, there is an operation mode in which playback is started from the beginning of a selected one of a plurality of segmented program information, and each subsequent segmented program information is sequentially reproduced in the recording order. A desired piece of segmented program information is selected from among a plurality of pieces of segmented program information, and the playback order of the pieces of information is stored in advance in the memory means.Then, the selected segmented program information is selected in accordance with the playback order stored in the memory means. It is assumed that an operation mode that allows playback, etc. can be adopted. And disk
Operations required for playback in each operating mode required by the player operator, or operations for storing the playback order of selected program information in the memory means, are normally performed by the disk player. This is done via various operation keys arranged on the operation panel section, etc.

Problems to be Solved by the Invention In the conventional disk player that is capable of taking various operation modes as described above, the desired one of each section program information recorded in the DAD is a plurality of program information selection keys for selecting the program information, a memory key for storing the playback order of the selected section program information in the memory means, and a play key for starting the playback operation of each section program information recorded on the DAD. key, a stop key for ending the playback operation of each segmented program information recorded on the DAD, etc.; Alternatively, when storing in advance the playback order of the selected segmented program information in the memory means, a procedure including multiple key operations is required.

For example, when playing back selected section program information from the beginning, first operate one of the multiple program information selection keys to select the desired section program information, and then operate the play key. A procedure is required for starting the playback operation from the beginning of the selected section of program information. In addition, before starting the playback operation from the beginning of the selected segment program information, the information reading means that reads the program information and address data from the DAD must first read the program information and address data from the DAD.
A so-called search operation is performed to bring the upper reading position to the beginning of the portion where the selected section program information is recorded.

Furthermore, when storing the playback order of the selected segmented program information in advance in the memory means, first select the desired segmented program information by operating any one of the plurality of program information selection keys.
Next, the memory key is operated to cause the playback order to be stored in the memory means, and the two key operations are repeated for each piece of segmented program information whose playback order is to be stored in advance in the memory means. Steps are required.

In this way, operations such as reproducing a selected one of the plurality of segmented program information recorded in the DAD or storing the reproduction order in advance in the memory means involve multiple key operations. Requiring such a procedure results in poor operability as a player, and is accompanied by the problem of making the operator feel troublesome.

In view of these points, the present invention is capable of selecting a desired piece of program information from among a plurality of pieces of segmented program information recorded on a disk such as a DAD, and storing the playback order in advance in a memory means, and A programming mode in which selected segmented program information can be played back in accordance with the playback order stored in the memory means, and a plurality of segmented program information recorded on a disk can be played back in accordance with the recording arrangement order from the playback start end. Starts playback from the beginning of the selected section of program information recorded on the disk, including when sequentially playing back each section of program information recorded on the disk, and sequentially plays each section of program information that follows in the order of recording. Furthermore, if necessary, it is possible to take an individual playback mode in which only a selected one of the plurality of segmented program information recorded on the disk can be played. It is a disk that significantly reduces the number of times that cumbersome key operations are required when each of these operating modes is taken, and that has significantly improved operability, including the simplification of such key operations.・The purpose is to provide players.

This program starts when the power is turned on to the player DP, and after starting, the continuous playback mode priority switch 32 is first set in the decision unit 101.
If it is determined that the continuous playback mode priority switch 32 is in the ON state, the process proceeds to process 102, where the continuous playback mode key 21 is pressed and the continuous playback mode is set. After turning on the continuous reproduction mode indicator light CL, the process advances to decision 103. On the other hand, the continuous playback mode priority switch 32 in the decision 101 is
If it is determined that the individual playback mode priority switch 33 is not in the ON state, the process proceeds to decision 104, where it is determined whether or not the individual playback mode priority switch 33 is in the ON state. If so, the process proceeds to process 105, where the individual reproduction mode key 22 is pressed to enter the individual reproduction mode, and the individual reproduction mode indicator light SL is turned on, and then the process proceeds to decision 103. If it is determined in the decision 104 that the individual playback mode priority switch 33 is not in the ON state, the process proceeds to process 106, where the programming mode key 23 is pressed to enter the programming mode. After turning on the indicator light PL, proceed to decision 103.

Decision 108 determines whether or not the continuous playback mode key 21 is pressed, and if it is determined that the continuous playback mode key 21 is pressed, the process advances to process 109 and turns on the continuous playback mode indicator CL. Along with turning on the light,
The individual playback mode indicator SL and the programming mode indicator PL are turned off and the process proceeds to decision 110. On the other hand, if it is determined in decision 108 that the continuous playback mode key 21 is not pressed, the process proceeds to decision 111. Then, it is determined whether or not the individual reproduction mode key 22 is pressed. If the decision 111 determines that the individual playback mode key 22 is pressed, the process proceeds to process 112 where the individual playback mode indicator light SL is turned on and the continuous playback mode indicator light CL and programming are performed.・Mode indicator light
Turn off the PL and proceed to decision 110. On the other hand, if the decision 111 determines that the individual playback mode key 22 is not pressed, the process advances to decision 113, where it is determined whether the programming mode key 23 is pressed, and the programming mode key 23 is pressed. If it is determined that it is, the program proceeds to process 114, where the programming mode indicator PL is turned on, and the continuous playback mode indicator CL and the individual playback mode indicator SL are turned off. , proceed to decision 110.

Decision 110 determines whether or not the carry key 26b has been pressed, and if it is determined that the carry key 26b has not been pressed, the process proceeds directly to decision 115, where it is determined that the carry key 26b has been pressed. If so, the process proceeds to process 116, stores 10 in the built-in selection key memory KM, and proceeds to process 117. In addition, if the total number of segmented program information recorded on the disc 1 used for reproduction exceeds 30, the carry key 26
Each time b is pressed, the number stored in the selection key memory KM is increased by 10. In the process 117, the content of the tens place stored in the selection key memory KM, for example, 1, 2, 3, or 4, is displayed on the tens place display section 36a' in the track number display section 36a, and the ``-'' is displayed in the digit display section 36a''
The code is displayed blinking until the direct key 26a is pressed. When the carry key 26b is pressed in this way, 10 or its multiple is temporarily stored in the selection key memory KM, and the 10's digit is displayed on the display section 36a' of the track number display section 36a. By making the "-" sign blink in "36a", even if more than 20 segmented program information are recorded on disk 1,
It is now possible to specify the track number corresponding to the segmented program information with a simple operation without increasing the number of direct keys 26a, and it is also possible to visually indicate that the 10's of the track number has been memorized. The next operation to be taken is suggested, and the direct key 26a
This prevents you from forgetting to press the button.

After passing through process 117, the process proceeds to decision 115, where it is determined whether or not the play key 24 has been pressed.If it is determined that the play key 24 has been pressed, the process proceeds to decision 118, where play (play from disk 1) is performed. (Program information playback status)
Determine whether it is in the middle or not. If it is determined that the game is not being played, the process proceeds to decision 119 (FIG. 4B), and if it is determined that the game is being played, the process proceeds to decision 120 (FIG. 4C). On the other hand, in decision 115, play key 24
If it is determined that is not pressed, the process advances to decision 121, and similarly to decision 118, it is determined whether or not play is in progress.If it is determined that play is in progress, decision 120 (the fourth
The process proceeds to FIG. C), and if it is determined that the game is not in play, the process returns to decision 103.

In process 107, which is proceeded when it is determined that the direct key 26a has been pressed in the above-described decision 103, the number stored in the selection key memory KM in the above-mentioned process 116 (0 if the carry key 26b is not pressed) ) and the number of the pressed direct key 26a, store the sum in the selection key memory KM, and select decision 1.
Step 22 determines whether the program is in programming mode. This determination is made by detecting whether the programming mode indicator PL is on or off; if the programming mode indicator PL is off, programming is not performed; It is determined that the mode is the continuous playback mode or the individual playback mode, and the process proceeds to process 123, where the target address is set to the beginning of the segmented program information represented by the track number stored in the selection key memory KM, and the process proceeds to process 124. In process 124, the track number stored in the selection key memory KM is cleared, and the process proceeds to process 125, where the play operation indicator light RL is turned on.

In the subsequent process 126, a muting control signal Cm is supplied to the program information processing section 8 to put the program information processing section 8 into a muting operation state, and the process proceeds to process 127. In the process 127, the reading position by the optical head 3 is determined in the process 123.
This is the target address set in . In order to reach the beginning of the section program information represented by the track number stored in the selection key memory KM, the reproduction address data D included in the reproduction address data Q obtained from the decoder 7 is compared with the target address. , if the two address data do not match, a control signal Cc is supplied to the reading position control section 6 in order to make them match. This results in
The reading position control unit 6 sends out a drive signal _C3 to cause the optical head 3 to perform a forward or reverse fast-feeding operation to rapidly move in the radial direction of the disk 1, and also sends out a drive signal _C2 to The tracking control means built into the optical head 3 takes a control state such as performing a tracking jump operation in the forward or reverse direction, and performs a search operation that causes the optical head 3 to reach the read position at the target address. Make them take actions in the state. After achieving such a control state, the process proceeds to decision 128,
It is determined whether or not the reproduced address data D matches the target address. If it is determined that the reproduced address data D does not match the target address, the process returns to process 127 and the above-mentioned optical head 3 performs the process again. Perform reading position control and repeat this process.
If it is determined that the reproduction address data D matches the target address, a process 129
Step 103 stops sending out the muting control signal Cm supplied to the program information processing section 8 to release the muting state of the program information processing section 8, and returns to process 103.

As a result, in the continuous playback mode or the individual playback mode, out of the plurality of segmented program information recorded on disk 1, the specified one can be played back according to the recording sequence order, or only the specified one can be played back. As a result, an audio signal A, which is a reproduction program information signal, is obtained at the output terminal 9.

On the other hand, if the decision 122 determines that the programming mode is selected, the process advances to decision 130 and the program information selection key 2 is pressed.
Programming total number flag F _Z indicating the total number of segmented program information specified by operation 6.
In other words, it is determined whether the total programming number flag F _Z has reached the total number of segmented program information recorded on the disk 1. Here, if it is determined that the total programming number flag F _Z is not the maximum, and therefore, if there is a possibility that further segmented program information to be provided for reproduction is specified, the process proceeds to process 131 and the total programming number flag F Increase _Z by 1 and process 13
Proceed to step 2 and flash the play operation indicator RL.

Next, proceed to process 133 and process 107
The contents stored in the selection key memory KM in
That is, the track number corresponding to the designated segmented program information is stored in the built-in programming memory PM at the position indicated by the total programming number flag _FZ obtained in process 131.
That is, the programming memory PM stores the playback order of selected pieces of program information recorded on the disk 1. The process then proceeds to process 134, clears the selected key memory KM, and returns to process 108. If it is determined in decision 130 that the total number of programming flags _Fz is the maximum, the process proceeds to process 134 without going through processes 131 to 133, executes the above-described process 134, and returns to process 108.

Here, by blinking the play operation indicator RL in process 132, when the programming mode is set, the track number corresponding to the category program information specified by operating the program information selection key 26 is selected. What has been stored in the key memory KM is visually represented and the next operation to be taken is suggested.

Decision 11 to proceed when it is determined in decision 118 that the play is not in progress.
9 (FIG. 4B), it is determined whether or not the programming mode is in the same manner as decision 122 described above. As a result, if it is determined that it is in programming mode, decision 13 is selected.
Proceed to step 5, and the total programming number flag F _Z is 0.
i.e. whether the track number corresponding to the specified section program information is
In other words, it is determined whether the playback order of the designated segmented program information is stored in the programming memory PM. Here, if it is determined that the total programming number flag F _Z is 0, that is,
If it is determined that the playback order of the designated segmented program information is not stored in the programming memory PM, the process proceeds to process 136 to switch the operating mode from the programming mode to the continuous playback mode and display the programming mode display. light
The PL is turned off and the continuous playback mode indicator CL is turned on, and in the subsequent process 137, the target address is expressed by the section program information recorded on the nearest playback start side of the disk 1, that is, the track number "1". After setting the segmented program information to the beginning of the program information, the process 125 and process 12 described above are executed.
6. Execute process 127, decision 128 and process 129 and return to decision 103.

This allows disk 1 to be played in continuous playback mode.
The plurality of segmented program information recorded in the program information is reproduced starting from the first one.

Further, if it is determined in decision 135 that the total number of programming flags F _Z is not 0, that is, it is determined that at least one track number corresponding to the designated segmented program information is stored in the programming memory PM. If so, proceed to process 138 and set a program play flag indicating the playback order of segmented program information.
After setting Fp to 1, the process proceeds to process 139. Process 139 includes programming the target address.
The track number stored in the position indicated by the program performance flag Fp of the memory PM is set to the beginning of the section program information, and the process 12
Step 5 follows, and the flow proceeds as described above.

As a result, under the programming mode, for the specified one of the plurality of segmented program information recorded on disk 1,
Reproduction is performed according to the reproduction order stored in advance in the programming memory PM.

On the other hand, if it is determined at decision 119 that the programming mode is not set, that is,
If it is determined that the mode is the continuous playback mode or the individual playback mode, the process advances to decision 140 and checks whether the track number displayed on the track number display section 36a is 0 or not, that is, whether the segmented program information has been specified. If it is determined that the track number is 0, that is, if the classification program information has not yet been specified, the program advances to process 137 and proceeds in the same manner as described above. If it is determined in decision 140 that the track number is not 0, that is, if classification program information is specified, the process proceeds to process 141 and the target address is set to the track number displayed in the track number display section 36a. After setting the beginning of the segmented program information to be displayed, the process proceeds to process 125, and the process proceeds in the same flow as in the case described above.

As a result, in the continuous playback mode or the individual playback mode, the first one or the specified one of the plurality of segmented program information recorded on disk 1, or the first one or the specified one. Only those that were previously played will be played.

In addition, the above-mentioned decisions 118 and 121
At decision 120, which is proceeded when it is determined that play is in progress, the playback address and
It is determined whether the reproduction address data D included in the data Q has changed to a new one, and if it is determined that the reproduction address data D has not changed, the process returns to decision 103. On the other hand, if it is determined that the playback address/data D has changed to a new one, the process proceeds to process 142, where the new playback address/data D is stored in the built-in memory, and the process proceeds to process 143. In process 143,
Based on the new reproduction address data D, the track number is displayed on the track number display section 36a.
Next, the process proceeds to decision 144, where it is determined whether the track number displayed on the track number display section 36a has changed. If it is determined that the track number has not changed, the process advances to decision 145, and the reading position by the optical head 3 is set to disk 1.
If it is determined that it is not located in the lead-out area, the process returns to the decision 103 and writes the program from disk 1. Continues information reproduction, and if it is determined that the information is located at the outermost recording section, the decision 1
The process advances to step 46 to determine whether or not the continuous playback mode is selected.
Here, if it is determined that the continuous playback mode is selected, the process proceeds to process 147, in which a muting control signal Cm is supplied to the program information processing section 8 in order to put the program information processing section 8 into a muting state, and further, the process 148, the transmission of the control signal Cc supplied to the reading position control section 6 and the motor control signal Cs supplied to the motor control section 11 is stopped, control over the optical head 3 is ended, and the program information from the disk 1 is reproduced. The operation is completed and the process returns to decision 103.

On the other hand, if decision 144 determines that the track number has changed, or decision 146 determines that the continuous playback mode is not set, the process advances to decision 149, where it is determined whether or not the individual playback mode is selected. If it is determined that the mode is not the individual reproduction mode, the process 147 and 148 described above are executed sequentially to finish the reproduction operation of the program information from the disk 1, and the process returns to the decision 103. The program proceeds to decision 150 to determine if it is in programming mode. If it is determined that the program is not in programming mode, the process returns to decision 103 and
Continue playing program information from disk 1,
If it is determined that the program is in the programming mode, the program proceeds to process 151, where the program performance flag Fp is incremented by 1, and the program proceeds to decision 152. At decision 152, it is determined whether the total programming number flag F _Z is smaller than the program performance flag Fp, and if it is determined that the total programming number flag F _Z is smaller than the program performance flag Fp, the process proceeds to process 147. Then, proceeding with the same flow as in the case described above, the operation of reproducing the program information from disk 1 is completed, and the process returns to decision 103. If it is determined that the total number of programming flags _FZ is not smaller than the program performance flag Fp, , process 13
Proceed to step 9 and proceed with the same flow as in the case described above, and play the designated one of the plurality of segmented program information recorded on disk 1 in accordance with the playback order prestored in the programming memory PM. continue.
